Description

WO 2009/109810 PCT/IB2008/004000 IMPROVED DISPOSABLE UNDERGARMENT WITH A FRONT OPENING PANEL Related applications This application claims priority to Provisional Application Serial No. 61/002,724, which was filed on November 9, 2007. Field The application relates to a disposable undergarment with a front opening panel. Background Disposable undergarments with open panels are well known in the art, such as baby diapers and incontinence briefs. The undergarments are produced as a flattened product with the rear and front panels detached. In order to wear the product, the rear panel is placed on the backside of the wearer, the front panel is brought through the crotch area to the front side of the wearer, and the front and rear panels are secured by overlapping front and rear panel ends and attaching them together with different types of adhesives, on the waist sides or mid front of the wearer. The main disadvantage of these products is that when the potential wearer is standing, it is complicated to put on the product and to wear the product so it fits properly. In cases where the person dresses themselves, it becomes even almost impossible. The solution for this disadvantage given by some manufacturers of such products is for the wearer to lean with their backside against a stable surface, such as a wall, and temporarily secure the rear panel to the back side of their body while the 1 front panel is brought forward to its place. Since most of the self-dressing wearers for these products are elderly users, this dressing method is far from comfortable. In order to overcome the above disadvantage, users may close the product prior to wearing it. Kimberly Clark, for example, sells a baby diaper which is ready to use as a pre-closed product where 5 the tapes can be re-opened, in order to ease baby diaper changing. The same solution applies to adults and babies. However, when the user wears panties, trousers, or pantyhose, that solution is impossible unless the user takes off the garment (panties, trousers or pantyhose), puts on the pre-closed undergarment/diaper, and then puts the garment on again. This process is complicated and creates discomfort especially when the changing of the undergarment is taking place in a public lavatory. 0 The need to wear an "open product" also arises with women wearing disposable underwear during menstruation while wearing trousers or pantyhose. Summary The present application offers a new aesthetically designed and more comfortable method for 5 wearing disposable undergarments such as panties, knickers, briefs, and diapers. In one embodiment, the application discloses an undergarment including: a waist band having an inner surface, an outer surface, a front side, a back side, a top portion, and a bottom portion, and a panel extending from the bottom portion of the back side of the waist band, the panel having a first end having a width, a front portion, and a back portion; and 0 a first securing mechanism for securing the first end of the panel to the bottom portion of the waist; wherein the first end of the panel is secured to the bottom portion of the waist band by the first securing mechanism so as to form an attachment therebetween which extends substantially entirely across the width of the first end, and wherein the disposable undergarment is made of one seamless 25 peice of a non-woven elastic or stretchable material so that, when the first end of the panel is secured to the waist band, the panel and the waist band are capable of stretching to conform and fit a body during use to hold the undergarment to the body. In another embodiment, the application discloses an undergarment including a waist band having a first end and a second end, and a panel extending from the bottom portion of the back side of 30 the waist band, the panel having a first end, a front portion, and a back portion. In this embodiment, the first end of the waist band is attached to the second end of the waist band by a first securing mechanism and the bottom portion of the waist band is secured to the first end of the panel by a second securing mechanism. A method for putting on a disposable undergarment is also described. The method includes: 35 providing a waist band including a front side, a back side, a top portion and a bottom portion; providing a panel extending from the bottom portion of the back side of the waist band, the panel having a first end having a width; 2 providing a first securing mechanism for securing the first end of the panel to the bottom portion of the waist band; putting on the waist band; pulling the first end of the panel toward the front side of the waist band; and 5 securing the panel to the waist band with the first securing mechanism so as to form an attachment therebetween which extends substantially entirely across the width of the first end; wherein the disposable undergarment is made of one seamless piece of a non-woven elastic or stretchable material.

Detailed Description Referring to Fig. 1, an undergarment 10 is provided. The undergarment 10 is made of one piece of material created by an upper part of the undergarment back panel 15, a front panel 12, and a waist band 11. Thus, the front of the undergarment includes a waist opening and a temporary opening in the bottom. This allows the wearer to first pull up the closed waist band over their pulled down undergarment (trousers, knickers, panties etc.) onto their body, so the waist band holds the garment on the wearer's body and no additional support for holding the undergarment on the body is needed. The undergarment 10 includes a waist band 11. The waist band 11 can be constructed in different ways. In one embodiment, shown in Figs 1-2, the waist band 11 is a single circular piece already closed and ready to be pulled up. In this embodiment, the waist band 11 may include reusable adhesive tabs (not shown), so that the wearer is able to adjust the undergarment on their body after putting it on to suit their specific size. In another embodiment, as shown in Fig. 3, the waist band 11 is open with two ends and the wearer attaches the ends together to create the closed waist band. In this embodiment, the first end 11 a and second end 11 b are secured to each other by a first securing mechanism 16, 17. The first securing mechanism 16, 17 may comprise double-sided tape. Alternatively, the first securing mechanism may be any suitable securing means, such as Velcro, adhesive, or snaps. 4 WO 2009/109810 PCT/IB2008/004000 In both embodiments, the waist band II further includes a top portion I1c and a bottom portion I1d. The waist band II also includes a front side 1 Ig which rests against the wearer's navel and a back side 1 Ih which rests against the wearer's back. The bottom portion I1d of the waist band may include a one end of a second securing mechanism 14. The front panel 12 may include the other end of the second securing mechanism 13. The second securing mechanism 13, 14 may be located on an inner surface I1e or an outer surface 11f of the waist band 11, as shown in Figs. 3 and 4. The second securing mechanism 13, 14 may comprise double-sided tape. Alternatively, the second securing mechanism may be any suitable securing means, such as Velcro, adhesive, or snaps. The undergarment 10 further includes a panel section having a front panel 12 and a back panel 15 extending from the bottom portion I1d of the waist band 11. The panel 12, 15 may have an hourglass shape. The front panel 12 may be folded to attach to the bottom portion 1ld of the waist band 11 by the second securing mechanism 13, 14. The second securing mechanism 13, 14 may either be located on either side of the front panel 12, or on the inner I1e or outer I f surfaces of the waist band 11. The undergarment may further include a pad 20, or any other suitable absorptive device, preferably located on the front panel section 12 of the undergarment 10. In one embodiment the pad 20, which is unified with the undergarment, is located entirely within the panel 12 of the undergarment 10, as shown in Figs. 3-6. In another embodiment, shown in Figs. 7-10, a pad 21 extends partially outside of the front panel 12. The adhesive side of the pad 21 creates an additional securing means to adhere the front panel 12 to the waist band 11. In operation, the undergarment 10 shown in Figs. 1 and 2 can be worn by pulling the closed waist band II over the wearer's knees and also over their bottom 5 WO 2009/109810 PCT/IB2008/004000 item of clothing while sitting or standing. Then, the panel 12, 15 of the undergarment, which is temporarily hanging from the back side of the waist band 11, can be brought forward via the crotch area and secured to the waist band 11 on the front side of the undergarment 10 by any suitable securing mechanism 13, 14. The leg openings are created when the panel 12, 15 of the undergarment is secured to the waist band 11. This method allows easier mobility wearing the undergarment while standing up, laying down, or sitting. In the embodiments depicted in Figs. 3-10, the first end 11 a and second end 1 lb of the waist band 11 are brought together and secured by securing mechanism 16, 17. Next, the front panel 12 is brought to the front between the legs and attached to the waist band, so that the product is ready to be pulled up to its place. The undergarment 10 may be made out of an elastic or stretchable material. The undergarment can be made as one layer with the open end front panel. Alternatively, the undergarment can be made out of more then one sheet, and can be combined out of several same or different materials or sheets. The undergarment can also be made out of any suitable materials such as cloth, elastomer, polymer or the like. Additional suitable materials that may be used with this application include natural rubber (e.g. latex), synthetic rubber, a fiber based material, or any materials mentioned in U.S. Patent Nos. 6,987,210, 7,354,424, and U.S. Patent Publication No. 2008/0150191, which are all hereby incorporated by reference in their entirety. If natural rubber, synthetic rubber or any other elastic or stretchable polymeric material is used to make undergarment 10, at least part or all of the surface of the material is preferably flocked with any suitable loose fibers such as cotton fibers or viscose fibers to create a smooth and cozy feeling for the wearer. Suitable flocking methods are described, for example, in U.S. Patent Nos. 6,987,210 and 7,354,424; 6 U.S. Patent Publication 2006/0113714; and U.S. application No. 2008/0150191, all which are hereby incorporated by reference in their entirety. The undergarment 10 may be manufactured by a number of different methods, including the methods described in detail in U.S. Patent Nos. 6,987,210, 7,354,424, and 6960740; U.S. Patent 5 Publication Nos. 2006/0113714 and 2008/0150191; and U.S. Patent Serial No. 12/053,040, all which are hereby incorporated by reference in their entirety. The present design allows the discharge of the undergarment by easily tearing the undergarment in the attaching regions, such as by detaching securing mechanisms 13, 14 between the panel and the waist band, and by detaching securing mechanisms 16, 17 on the waist band 11. 0 The present figures represent the basic concept of the innovative design which is not limited to the specific shape and style, or according to gender styles.
